An apparatus is disclosed for improving the transportability of a hydrocarbon stream by reducing its viscosity. The apparatus comprises a reactor vessel useful for providing an incremental amount of heat to a hydrocarbon stream by the introduction of an oxidizing agent into the core portion of the stream. The reactor comprises an influent conduit and an effluent conduit in heat exchange relation with each other, at least one oxidant injection nozzle located in either or both the influent and/or effluent conduits, a conduit to transport oxidant to the nozzles and a valve in the oxidant conduit to control oxidant flow to the nozzles. The reactor can also contain temperature monitors in the influent and/or effluent conduits and an oxidant flow controller device responsive to output from the temperature monitors and adapted to adjust oxidant flow to maintain temperatures in the reactor reaction zone within a preselected range.
A vertical tube reactor apparatus disposed within a substantially vertical well bore, said apparatus being suitable for reducing the viscosity of hydrocarbons, said apparatus comprising: (a) an influent conduit in fluid communication with an effluent conduit comprising concentrically arranged inner
A vertical tube reactor apparatus disposed within a substantially vertical well bore, said apparatus being suitable for reducing the viscosity of hydrocarbons, said apparatus comprising: (a) an influent conduit in fluid communication with an effluent conduit comprising concentrically arranged inner and outer conduits, each having an upper and a lower zone, wherein said influent conduit is said inner conduit and said effluent conduit is said outer conduit, said influent conduit adapted to receive an influent hydrocarbon stream and conduct said influent stream substantially downward, and said effluent conduit adapted to conduct an effluent product stream substantially upward, wherein said conduits provide heat-exchange contact between influent stream and said effluent product stream to produce a heated influent stream; (b) an oxidant injection nozzle located within said effluent conduit so as to introduce oxidant into the core portion of said heated influent stream substantially parallel to the flow of said stream to produce an effluent product stream; (c) means for sensing temperature located within at least one of said lower zones downstream from said nozzle, said means producing an output proportional to said temperature; (d) a conduit extending to the surface of the well bore and being connected to the nozzle for conducting oxidant from the surface of the well bore to said nozzle, said oxidant conduit including a flow metering means and being located within said well bore and travelling substantially parallel to said influent and effluent conduits; and, (e) a means for controlling the flow rate of said oxidant within said oxidant conduit, said control means being operatively associated with said metering means and said temperature sensing means so as to be responsive to the output from said temperature sensing means and adjust said oxidant flow rate in a preselected proportion to said output.
